In any case, using "end" instead of "pass" is a poor tradeoff. Instead of

Yes, well, some of us wouldn't mind!
'end' to terminate a block can be emulated of course:
end=0
def fn(a):
if a<=1:
return 1
else:
return fn(a-1)
end
end
And in this example it wouldn't impact on performance as it is not
evaluated.
But although it can make source code look more conventional, it would
not be supported by the language (repeated, out of place or missing
'end' lines are not an error). And an empty block will still need pass.
